Usage

Two inputs are necessary for this relational evaluation to take place.

The order of inputs is relevant for this tool.

Syntax

LessThan (in_raster_or_constant1, in_raster_or_constant2)

Parameter

Explanation

Data Type

in_raster_or_constant1

The input being tested to determine if it is less than the second input.

A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment.

Raster Layer; Constant

in_raster_or_constant2

The input against which the first input is tested to be less than.

A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment.

Explanation

Data Type

out_raster

The output raster.

The output cell values will be either integer 0 or 1, or NoData if any input cell value is NoData.

Code sample

LessThan example 1 (Python window)

This example performs a Relational less-than operation on two Grid rasters and outputs the result as a TIFF raster.
